Thank you Charlie and thank you all for joining us. Corcept had an excellent quarter. As Charlie mentioned our revenue increased 72% to 27.6 million. We generated GAAP net income of $0.04 per share and non-GAAP net income of $0.06 per share. Our cash and investments increased by $5.7 million even as we funded our growing clinical development programs. We now raise our 2017 revenue guidance to between $125 million and $135 million and we continue to anticipate significant growth in 2018, 2019, and beyond. These results are especially impressive because we produced them in the first quarter of the year which is our most challenging quarter commercially. Every January many insurance companies require patients to obtain reauthorization of their Korlym coverage. This practice is common for often medications. Even though we help patients navigate this bureaucratic process and in many cases insurance coverage continues without interruption, some patients briefly lose coverage. In keeping with our guiding principle that the health of our patients comes first, we provide Korlym free of charge to patients whose insurance coverage temporarily lapses. But our first quarter revenue was reduced while we cleared this annual insurance hurdle. As was true in prior quarters, our Cushing's syndrome business excelled because our clinical specialist continue to become more productive. Cushing's syndrome is a complex disease. Even a highly skilled clinical specialist must spend significant time with a physician, often five to seven visits before that physician writes their first Korlym prescription. Since Cushing's syndrome is a chronic illness and Korlym is a chronic treatment for it, it takes some time often four months or longer before the full impact of the patient is seen - full economic impact of the patient is seen. We now have 31 clinical specialists and continue to hire experienced high-quality candidates as we identify them. The latest class of 5 which trained in the fourth quarter of 2016, we look forward to their contributions later this year and beyond. But I do not want my justified attention to the talent and hard work of our commercial team to have skewered two other fundamental reasons for our success. First, Korlym is an ineffective medication. For almost all patients it works very well. For some, it is a life transforming. As you'll recall Cushing's syndrome is caused by a tumor that produces either excess cortisol or ACTH, a hormone that causes the body to produce cortisol. Symptoms vary from patient to patient and include impaired glucose tolerance, high blood pressure, central obesity, increased fat around the neck, thinning arms and legs, weak muscles and severe fatigue. Irritability, anxiety, cognitive disturbances and depression are also common. Hypercortisolism can affect every organ system in the body and can be lethal if not treated. Korlym works by competing with cortisol at the glucocorticoid receptor, GR for short. The receptor to which cortisol binds when cortisol levels are elevated. Korlym modules the effects of cortisol and a patient's symptoms abate. In our Phase 3 trial, 87% of the patients as adjudicated by independent outside experts experienced significant clinical improvement. Remember, many of our patients began taking Korlym after therapies such as ketoconazole, a generic anti-fungal agent and has the side effect of lowering cortisol levels by inhibiting cortisol production failed them. The fact that Korlym can help patients after the traditionally used cortisol synthesis inhibitors have failed it's something physicians remember and it's one of the reasons first time prescribers often become multiple prescribers. A second important reason for our growth is that the physicians have become more sensitive to the dangers of less severe hypercortisolism which is significantly more prevalent in the severe cases that until recently defined most doctors understanding of the disorder. It's increasingly understood that even moderate or mild cortisol excess, a condition many physicians use to dismiss with a watch and wait stance, is highly likely to produce detrimental symptoms over time. Important papers published by Dr. Diana Lopez in the Annals of Internal Medicine and by Dr. Valentina Morelli in the Journal of Clinical Endocrinology and Metabolism reviewed the health outcomes of patients with mildly accessible cortisol activity and down significantly increased morbidity and mortality. Awareness of this fact is causing many physicians to take a second look at patients in their care who exhibit one or more symptoms of Cushing's syndrome such as glucose intolerance or hypertension but who have not responded to conventional therapies for those conditions. In many cases they discover that these patients have demonstrably excessive cortisol activity. As many of you know we are advancing a proprietary compound CORT125134 that we believe will greatly expand the market for cortisol modulators as a treatment for Cushing's syndrome. CORT125134 is a selective cortisol modulator that may offer Korlym benefits without some of its drawbacks. Korlym modulates activity at the progesterone receptor, abbreviated as PR, as well as GR. In some women, Korlym's affinity for PR causes endometrial thickening and irregular vaginal bleeding. These side effects are not life threatening and are manageable but patients and physicians would strongly prefer to avoid them. Affinity for PR is what makes the active ingredient in Korlym the abortion pill. A drug that effectively modulated cortisol but had no affinity for PR and none of the abortion pills medical and political toxicity would undoubtedly be a superior medication. CORT125134 Phase 2 trial is a single-arm dose ranging study that will enroll 30 patients at sites in the United States and Europe. Enrolment is in progress and we expect results by the end of this year. We are also developing a clear validated assay that we believe will become a powerful tool for diagnosing and optimally treating patients with Cushing's syndrome. The assay will measure activity of the gene FKBP5. Cortisol stimulates FKBP5 gene expression. In healthy subjects in our Phase 1 study, FKBP5 levels increased substantially when patients were administered prednisone, a synthetic analog to cortisol but remained unchanged when Korlym or CORT125134 was co-administered with prednisone. This is a very strong indication that CORT125134 will act similarly to Korlym in treating patients with Cushing's syndrome. Korlym works by reducing cortisol's activity. This is obvious to the doctor as they see their patient symptoms improve. However because GR modulators like Korlym or CORT125134 do not reduce cortisol levels, the patient's improving health is not accompanied by a decrease in cortisol levels. Our expectation is that FKBP5 expression will decline as cortisol actively returns to normal levels and the patient's symptoms abate. We believe our assay will among other things help physicians monitor the reduction in cortisol activity and arrive at an optimal dosing regimen. We expect work on this - we expect to complete work on this assay this year. I will now turn to our oncology program. There are two mechanisms by which cortisol modulation may prove to be an effective oncology therapy. First, in cancers or tumors expressed GR such as triple negative breast, ovarian, and pancreatic cancer, cortisol stimulates genes that retard apoptosis, the programmed cell death that many chemotherapies are intended to provoke. Preventing the stimulation of these apoptosis suppressing genes by adding a cortisol modulator to a chemotherapy regimen should allow that regimen to achieve its optimal effect. Second, cortisol modulation may help the immune system fight cancer. As you know there is much interest in oncological therapies that stimulate the body's immune system to fight the disease. Cortisol suppresses the immune system. The physiological and psychological stress of cancer and its treatment raise cortisol activities above normal levels creating even greater immunosuppression. Cortisol modulators counter this effect. And cancers that are particularly susceptible to the body's immune response such as melanoma, cortisol modulation may be useful even without a companion agent. The phase 1/2 trial of Korlym in combination with eribulin to treat patients with triple negative breast cancer that we completed last year showed the combination of Korlym and chemotherapy was clinically active and deserved further study. Investigators at the University of Chicago are now leading a definitive study. With funding from Celgene, they and their investigators are conducting a double-blind placebo controlled multicenter Phase 2 trial of Korlym in combination with nab-paclitaxel, Celgene's drug ABRAXANE in 64 patients with advanced triple negative breast cancer. We are providing Korlym. While the University of Chicago researchers investigate the use of Korlym in triple negative breast cancer, we are advancing CORT125134 in combination with ABRAXANE to treat patients with a range of solid tumor cancers. Our trial is currently in its dose finding phase. We expect open expansion cohorts by the end of the year. Although the disease targets have not yet been chosen, triple negative breast cancer, ovarian cancer, and pancreatic cancer are likely targets. In addition, we may initiate a clinical trial of CORT125134 in combination with a checkpoint inhibitor. Cortisol modulation may also help treat castration resistant prostate cancer which is a particularly serious form of the disease. Because androgen stimulate prostate tumor growth, androgen deprivation also known as chemical castration is a common treatment for prostate cancer. Investigators at the University of Chicago showed and Charles Sawyers' group at Sloan Kettering confirmed that very early in treatment with the androgen receptor antagonist enzalutamide colonies of tumor cells emerge in which cortisol through its stimulation of GR is the primary growth factor. Combining a cortisol modulator with an androgen modulator such as enzalutamide, the Astellas Medivation drug, XTANDI from the outset of treatment may block this cancer escape route. University of Chicago investigators are leading an 84 patient controlled multicenter Phase 2 study of Korlym combined with XTANDI to treat patients with metastatic castration-resistant prostate cancer. The Department of Defense and the Prostate Cancer Foundation are funding the trial. Astellas is providing XTANDI, we are providing Korlym. Following very promising preclinical results, we are also advancing one of our own proprietary selective cortisol modulators, CORT125281 as a treatment in combination with XTANDI for this disease. Phase 1 for this compound should begin next quarter. As a reminder, we have exclusively licensed intellectual property from the University of Chicago covering the use of any cortisol modulator in combination with any anti-cancer agent to treat patients with triple negative breast cancer and have any cortisol modulator and any androgen deprivation agent to treat castration-resistant prostate cancer. For the past few quarters, I've reminded you that CORT118335 another of our proprietary selective cortisol modulators is very active in animal models of fatty liver disease and antipsychotic induced weight gain. Serious disorders that affect millions of people in the United States. CORT118335's phase 1 trial will begin early next quarter. Should the results be positive, I'll have more to say about our plans for advancing this exciting compound in coming quarters. To sum up, Corcept had an excellent first quarter. Despite the commercial challenges posed at the start of every year by insurance reauthorizations, our revenue grew to 27.6 million, an increase of 72% from the first quarter of last year. We have increased our 2017 revenue guidance for the second time this year to between $125 million and $135 million. We generated a GAAP profit for the quarter of $4.4 million and we expect - continue to expect our Cushing's syndrome revenue to fully fund our planned activities. We will soon have results of our phase 2 trial of CORT125134 in Cushing's syndrome. CORT125134 promises to offer Korlym's efficacy, but without some of its side effects. Importantly, it is also not the abortion pill. We are also developing a gene expression assay that will help physician's diagnose and more effectively treat patients with the disorder. Successful development of CORT125134 and of our assay will, in our view, significantly expand the Cushing's syndrome market and extend our hold on it for years to come. University of Chicago investigators are leading a Celgene financed double-blind placebo-controlled multi-center phase 2 trial of Korlym in combination with Abraxane. Our trial of CORT125134 in combination with Abraxane continues to enroll patients and we expect open expansion cohorts by the end of the year. University of Chicago investigators are also leading a multi-center controlled phase 2 trial pairing Korlym with Xtandi to treat patients with castration-resistant prostate cancer. We plan to begin phase 1 testing of CORT125281 and if results are positive, begin a phase 2 trial of CORT125281 in combination with Xtandi to treat patients with a serious disease. Finally, one of our most promising proprietary compounds CORT118335 will begin its phase 1 trial early next quarter. If the results are positive, we will advance it to phase 2 for the treatment of fatty liver disease and potentially other metabolic disorders. Thank you. I'll stop now to answer questions.
